1. CarePalm – A Computerised Patient Charting System Tracy O’Neill, B.Sc. (Hons.) M.Sc. Research Project Presentation (COM-865-M4) Faculty of Computing & Engineering University of Ulster, Magee

2. Introduction Current System Adoption of a Portable Computer Based Charting System Benefits Offered by Computerisation of Patient Records www.patientsafetyalliance.scot.nhs.uk

3. Aims and Objectives Develop application for handheld device Provide ease of access to patient charts Enable modifications through the handheld device Incorporate XML to store patient data Security

4. Background Pervasive Healthcare XML and Interoperability Security The Modified Early Warning System (Mews) Joos and Whiteman (2006) Kreps and Richardson (2007) Al-Salqan (1998) Thorpe et al. (2006)

5. Requirements Analysis Questionnaires 57% said current system was either good or very good 71% had issues with deciphering various handwriting on patients charts Over 50% of respondents said they would feel confident in using PDA’s to assess patient charts Informal Interviews To gain knowledge on existing method To gain understanding of particulars held on patient’s chart

6. CarePalm Architecture

7. CarePalm Implementation Designed within Visual Studio Code developed in C# Data represented in XML files Modified Early Warning System (MEWS)

8. Evaluation and Testing Functionality Testing Conducted during all stages of development Test cases completed on each form to ensure CarePalm’s functionality Usability Testing Nurses enlisted to test CarePalm 100% said they could update patient records easily 75% stated that CarePalm’s usability is very good with the remaining 25% saying it was good

9. Relation to Other Work Clinical Care Classification (CCC) Bedside Computer proposed by Saba and Feeg (2005) Pyxis Patient Station is implemented at Holy Name Hospital in New Jersey, USA Nurse.com (2005) www.utmb.edu

10. Conclusion and Future Work Successful prototype Factors hindering implementation within the UK National Health Service Incorporate data mining software Implement on tablet PC Kreps and Richardson (2007)
